Vintage Navajo turquoise bead necklace and pin charm

I put these 2 together. Wear them that way or separately! The vintage chain is 36” long with turquoise colored balls in slightly varied colors. Stamped 925. Charm is also a pin. It’s approx. 1.85” wide x 1.85” long. I don’t see a 925 stamp on the pin, but this vintage piece tests positive for silver. No flaws. Some tarnish, which I love! A great layering piece!
